Walmart rewrites content rules for AI-driven shopping.
Walmart has released new content guidelines that take effect now, and sellers report titles over 90 characters being rejected ahead of a formal mandate. Walmart's standardisation of Sparky, its AI shopping agent, whose weekly active users are up over 100% quarter-on-quarter.
Why it matters for advertisers
For you, this means content built for AI parsing now decides visibility, so restructure titles and content to the new format first. Titles: open format replaced by Brand + Product Line + Key Features + Size + Count, with rejections reported above 90 characters Descriptions: cut from 4,000 characters to 200 words, repeating the product name Images: text overlays required on secondary images, plus a dimension image for every item Alt text: keyword, colour, material, and GTIN are now required

Spencer Millerberg supplies the linked detailed guideline analysis. Max Sinclair supplies a separate analysis of title requirements and AI shopping. Both contributions are retained, without asserting that either was the first public reporter.
Attribution evidence and limitations
Read both posts in full. Spencer details seven guideline changes; Max discusses title constraints and cites Walmart’s CFO. Tagged brand partners are recipients, not co-authors.
Each post identifies its author and profile. The broader guideline analysis is linked first, followed by Max’s distinct interpretation.
Visually inspected the graphic. It names John David Rainey as the quoted CFO, cites Walmart’s Q1 FY27 earnings call and carries AZOMA.AI branding. Rainey is the quoted speaker, not the author of either LinkedIn analysis. The individual graphic designer is unverified.
